First, Thanks to OBJ for the message about the manual. Now I need to find a gas tank with cap and keeper chain. This was discontinued in 1979. The part numbers are 279-097 or 279-089. It is a 1968 "Mate" 1 1/2 hp (no model no.) serial #1802s-e06635. Does anyone know where I can find this tank? Thanks, Brill from Hondo, Tx
